This page lists a few online calculators that are useful to lab users.
Fabrication Processes & Converters
- Thermal Oxide Calculator (BYU)
- Conversion of Pressure Units (calculatoredge.com)
- Mean Free Path tables (Pfeiffer Vacuum)
Refractive Indices
- LuxPop.com
- RefractiveIndex.info
- Filmetrics Inc.
- Ioffe Institute
- nk.py (Demis D. John)
- Python functions for returning n (ref. idx.) & k (ext. coeff.) of various NanoFab thin-films at a specified wavelength (dispersion models).
Material Parameters
- WebElements: Compounds
- Boiling points of various compounds can tell you how volatile an etch product may be in a reactive ion etch, or whether they need to be wet-etched instead.
- Physical Properties of Semiconductors (Ioffe Institute)
Wet Etching
- Transene Inc. Chemical Compatibility Chart
- A.R. Clawson, "Guide to references on III±V semiconductor chemical etching", 2001
- Enormous review of published wet etches of many semiconductors and alloys. The only thing it's missing is a hyperlinked table of contents.
General Calculators
- Anaconda Python
- A free Matlab-like IDE and GUI, using the Python language. The Spyder interface is modeled after Matlab.
- Includes the scientific Python libraries needed for array math (numpy), plotting (matplotlib), data science (pandas) and many others. Many open-source packages are available to extend capabilities.
- Octave Online Interpreter (online-utility.org)
- A Matlab-like command-line interface, powered by Python Octave.
Python Scripts
These scripts are best run in the Spyder IDE, which is easily installed via Anaconda, Python(X,Y), or direct compiling using a command-line package manager.
- Keithley I-V Sweep
- Sweep voltage and plot current vs. voltage using a Keithley SMU. Already installed at the Probe Station in Bay 4 (Use Python(X,Y) to run), and on the QFI Thermal Microscope.
- QFIScope Thermal Analysis
- Import 2D temperature data from the IR Thermal Microscope (QFI) and plot temperature profiles at specified locations.
- Laser Etch Monitor Simulation in Python
- Simulate your laser endpoint signal as you dry-etch through a stack of thin-film layers.
